This knowledge base composed byMiniToolintroduces a web connection switch technology named port mirroring to you.
It involves the meaning, functions, advantages, as well as restrictions of port mirroring.
Define Port Mirroring
What Is Port Mirroring?
It can also be applied to mirror both outbound andinbound trafficon single or multiple interfaces.
Port mirroring is supported by nearly all enterprise-class switches, also managed switches.
How Does Port-Mirroring Work?
A port mirror copies Layer 3 IP traffic to an interface.
In this post, we will show you how to do this job using different methods.
Port Mirroring vs Traffic Sampling
Port mirroring is different from traffic sampling.
Packets based on that key are sent to a cflowd server.
Other computers that dont join the communication wont see the traffic.
So read it carefully.
Port Mirroring Performance Limitation
Mirroring only the packets needing analysis reduces the possibility of reducing overall performance.
If you mirror traffic from multiple ports, the mirrored traffic may exceed the capacity of the output interface.
Then, the overflow packets are dropped.
